KPM’s battery EOL testing systems automate these processes with real-time monitoring, trend analysis, and safe discharge protocols. This enables accurate decision-making for second-life applications, such as stationary storage, or safe recycling, aligning with circular economy goals. 17 What do you mean by Understanding the Thermal Runaway Effect? End-of-life (EOL) testing for EV batteries is crucial to determine whether a battery should be reused, repurposed, or recycled. This involves evaluating the battery’s State of Health (SoH), residual capacity, internal resistance, and thermal behavior. Typically, a battery is considered at end-of-life when its usable capacity drops below 70–80% of its original rating. EOL testing includes controlled charge/discharge cycles, impedance analysis, and thermal profiling under simulated real-world loads. It also verifies the integrity of the Battery Management System (BMS) and checks for cell imbalance, swelling, or leakage. This testing helps classify batteries for secondary applications like energy storage or ensures safe recycling of critical materials. KPM’s battery testing systems provide automated, accurate EOL assessment with programmable protocols, multi-parameter monitoring, and safety interlocks, enabling OEMs and recyclers to make informed decisions about battery reuse, life extension, or disposal. 18 Difference between Battery Energy Density and Safety: A Testing Perspective? As energy density increases in lithium-ion batteries to meet the demands of EVs, aerospace, and portable electronics, safety risks also rise. Higher energy density means more power is stored in the same space, which can lead to thermal runaway, fire, or explosions if not properly managed. From a testing perspective, it is critical to balance performance with safety through: Thermal abuse tests to simulate overheating Overcharge/overdischarge tests to detect BMS failure scenarios Short-circuit and impact testing to assess mechanical protection Internal resistance and SoH testing to identify degradation risks early Leakage and enclosure integrity tests to prevent moisture or gas ingress Testing protocols per UN38.3, IEC 62133, and UL 2580 ensure that high-energy cells meet strict safety thresholds. KPM’s battery testing solutions are designed to test both high-capacity and high-safety requirements, providing real-time monitoring, automated safety shutdowns, and environmental stress simulations to ensure safe, high-density battery deployment. 19 What Makes a Good Battery Service Center?

During a circuit breaker timing test, the opening and closing times of main and auxiliary contacts are measured to assess the breaker's mechanical and electrical performance. The test simulates real fault or operation conditions, records response times (e.g., O, C, O-C-O), and analyzes contact synchronization, bounce, and trip coil current. These measurements reveal issues like slow operation, wear, or misalignment. Advantages include early fault detection, improved safety, reduced downtime, and compliance with IEC/ANSI standards. KPM offers precise timing test equipment with advanced diagnostics, helping utilities and industries maintain system reliability and extend breaker life through data-driven maintenance planning. 02 What means measuring contact resistance in Circuit Breakers ? A contact resistance test measures the electrical resistance across closed contacts of a circuit breaker. Low resistance ensures efficient current flow with minimal losses or overheating. High resistance can indicate pitting, corrosion, or poor contact pressure. This test helps detect internal issues not visible externally. It’s essential for preventing energy losses, overheating, and eventual failure during load or fault conditions. Regular testing ensures optimal breaker performance, safety, and longevity. KPM offers contact resistance test equipment with high accuracy and data logging, enabling predictive maintenance, faster troubleshooting, and compliance with IEC/IEEE standards across substations and industrial power systems. 03 What is the use of both side ground feature in contact resistance meter ? The both-side ground feature in a contact resistance meter allows the tester to connect the instrument’s ground reference on both ends of the circuit breaker contacts simultaneously. For Example:- - Eliminate interference and noise caused by stray currents or electromagnetic fields. - Improve measurement accuracy by ensuring a stable, low-resistance ground path. - Prevent false readings that may occur if only one side is grounded. - It increases the safety of the operation. - KPM’s contact resistance meter CRT 200 G use this feature to deliver precise, repeatable readings critical for assessing contact health and ensuring reliable breaker operation. 04 Why is understanding Coil Current Analysis in Breaker Testing important ? Coil current analysis involves measuring the current drawn by the trip and close coils during circuit breaker operation. This current signature helps diagnose the breaker’s mechanical and electrical health. Changes in current shape, peak value, or duration can reveal issues like sluggish movement, coil burnout, weak springs, or mechanical obstructions. Analyzing the coil current curve provides early warnings of potential failure before timing or contact issues become visible. It enhances predictive maintenance and helps avoid costly downtime. KPM’s test systems capture detailed coil current waveforms, enabling precise diagnostics, improved reliability, and safe operation of critical power systems. 05 How to do Dynamic Contact Travel Analysis ? Dynamic contact travel analysis measures the real-time movement of a circuit breaker’s main contacts during operation using motion sensors or transducers. It captures parameters like stroke, velocity, overtravel, rebound, and contact wipe. This test reveals mechanical wear, misalignment, or sluggish movement that timing tests alone can miss. It ensures the breaker’s mechanical integrity, proper contact engagement, and smooth operation under stress. KPM’s breaker analyzers support dynamic travel analysis with high-resolution sensors and software that visualizes motion curves. This allows for accurate diagnostics, preventive maintenance, and verification that breakers meet design and safety standards. 06 What is Vacuum Interrupter Testing ?What is its Life Cycle and Failure Modes? Vacuum interrupters (VIs) are critical components in medium-voltage circuit breakers, responsible for arc extinction. Though sealed for life, their performance can degrade over time. Life Cycle: VIs have a defined mechanical and electrical life—typically 10,000+ operations or a set number of fault interruptions. Factors like switching frequency, fault levels, and contact wear influence lifespan. Failure Modes: Loss of vacuum (leakage) Contact erosion or misalignment Internal flashover or dielectric breakdown Testing: KPM offers vacuum interrupter testers to check vacuum integrity using high-voltage AC/DC or magnetron-based methods, ensuring reliability, safety, and timely replacement decisions. 07 Why you Shouldn’t Ignore Pre-Insertion Resistor Testing ? Pre-insertion resistors (PIRs) reduce inrush currents during circuit breaker closing, protecting equipment from voltage transients and mechanical stress. Ignoring PIR testing can lead to undetected resistor failure, delayed insertion, or complete bypass—compromising system stability. Regular PIR testing verifies correct resistor engagement, timing, and resistance values. It ensures effective damping of switching surges, especially in capacitor bank or transformer applications. KPM’s breaker analyzers can assess PIR timing and resistance performance with precision, helping prevent equipment damage, extend asset life, and maintain reliable power system operation. Skipping this test risks hidden failures and costly breakdowns. 08 Differences Between Testing SF6, Vacuum, and Oil CBs ? Here’s a concise comparison of testing SF6, Vacuum, and Oil Circuit Breakers (CBs): SF6 CBs: Tests focus on gas pressure, density, and leakage, plus timing, contact resistance, and gas quality analysis. SF6 ensures excellent arc quenching. Vacuum CBs: Emphasis on vacuum integrity testing, contact resistance, timing, and coil current analysis. Vacuum interrupters have a sealed, long-life design. Oil CBs: Requires insulation and oil quality tests, contact resistance, timing, and sometimes oil dielectric strength checks. Oil acts as arc quenching and insulation medium. KPM offers specialized test equipment tailored for each CB type, ensuring accurate diagnostics, maintenance, and safety compliance. 09 Difference between Circuit Breaker Analyzer and Manual Timer – Pros & Cons? Circuit Breaker Analyzer Pros: High accuracy and repeatability Measures multiple parameters (timing, coil current, contact resistance) Data logging and analysis software Detects subtle faults and trends Faster and safer testing Cons: Higher initial cost Requires some training to operate Manual Timer Pros: Low cost and simple to use Portable and no power needed Cons: Limited accuracy and precision Measures only basic open/close timing No data recording or advanced diagnostics Prone to human error KPM provides advanced analyzers that save time, improve safety, and offer detailed diagnostics for better maintenance decisions. 10 How Temperature and Environment Affect CB Test Results ? Temperature Effects: Cold temperatures can stiffen mechanical parts, causing slower operations and longer timing. High temperatures may reduce coil resistance, affecting current measurements. Extreme temps can alter contact resistance readings due to material expansion or contraction. Environmental Factors: Humidity can cause corrosion or moisture ingress, affecting insulation and contacts. Dust and contaminants can interfere with mechanical movement or electrical contacts. Vibrations or electromagnetic interference may distort sensitive measurements.

Tipik Paratoner, bir yüksek voltaj terminaline ve bir topraklama terminaline sahiptir. Bir yıldırım dalgalanması (veya anahtarlama dalgalanması) güç hattı boyunca Parafudur'a gittiğinde, dalgalanmadan gelen akım, çoğu durumda Toprağa olmak üzere Parafudr üzerinden yönlendirilir. Koruma başarısız olursa veya yoksa, elektrik sistemine çarpan yıldırım, iletim hatlarına zarar verebilecek ve ayrıca transformatörlere ve diğer elektrikli veya elektronik cihazlara ciddi hasar verebilecek binlerce kilo Volt verir. Gelen güç hatlarında yıldırımın ürettiği aşırı voltaj yükselmeleri, elektrikli ev aletlerine de zarar verebilir, bu nedenle Paratonerin bütünlüğü için çok önemlidir. Şu anda toplam kaçak akımın (kapasitif ve dirençli akımlar) izlenmesi birçok kamu hizmeti kuruluşu tarafından kullanılmaktadır. Kaçak Akım Monitörleri, Parafudrların Kaçak Akımını ölçmek için kullanılır ve yüksek kaçak akım durumunda Parafudrlar değiştirilir. Bununla birlikte, tamamen kapasitif olan toplam kaçak akım Parafudrların sağlığını tam olarak göstermediğinden, bu yöntemin kusursuz bir yöntem olmadığı düşünülmektedir. Toplam kaçak akım değerinin üreticiler tarafından belirlenen sınırın altında olmasına rağmen Parafudrların patladığı durumlar olmuştur. Direnç akımı toplam akımın %15-30'udur ve kapasitif ve dirençli akımlar 90 derece yüz kaymasında olduğundan, dirençli akımdaki önemli değişiklik bile toplam akımda çok küçük artışlara neden olur. Bu nedenle, toplam kaçak akımın izlenmesi, ZnO diskin bozulmasını tam olarak göstermeyebilir. Uzun lineer ZnO diskin bozunması, temel frekansın sistem voltajı uygulandığında genellikle kaçak akımda harmoniklere yol açar. Üçüncü harmonik dirençli akım ölçümü, üçüncü harmonik bileşenin toplam kaçak akımdan filtrelenmesine dayanır. Yaklaşık 500 mikro amper mertebesindeki kaçak akımın genellikle güvenli olduğu kabul edilir. Kaçak akımın dirençli kısmı veya güç kaybı, aşağıda verilen çeşitli yöntemlerle belirlenebilir: Referans olarak bir voltaj sinyali kullanma Bir voltaj sinyali kullanarak kapasitif bileşeni telafi etme Üç fazın kaçak akımını birleştirerek kapasitif kompanzasyon Üçüncü dereceden harmonik analizi Güç kayıplarının doğrudan belirlenmesi Gerilimdeki harmonikler için kompanzasyonlu üçüncü dereceden harmonik analizi “Dirençli akım” bileşen hesaplamaları ile Gelişmiş İzleme Sistemi. Gelişmiş teşhis yöntemlerinin kullanılması, arıza olasılığını büyük ölçüde azaltır ve dolayısıyla insan ve para kayıplarını önler. Bu nedenle Parafudrların durumunun düzenli zaman aralıklarında, Parafudrun enerjisi kesilmeden hizmette olan sürekli kaçak akımın rezistif bileşeni ölçülerek kontrol edilmesi arzu edilir. Referans olarak “Gerilim Sinyali” ilkesine dayalı cihazlarla güvenilir ölçümler elde edilir. LA'nın düzenli olarak izlenmesi, 66 kV ila 765 kV trafo merkezlerinde birçok arızayı önlemiştir. Bu akımın değerleri normalde mili amper kesirlerinden birkaç mili ampere kadar değişir ve değeri Parafudurun bozulmasının bir göstergesi olan dirençli akım değişimleriyle karakterize edilir. Bu kaçak akımın rezistif bileşeni, yaşlanmaya neden olan ve nihayetinde Parafudr arızalarına neden olan farklı gerilimler nedeniyle artabilir. Sık Sorulan Sorular ( SSS ) FAQ about lightning arrester testing : 01 What is the purpose of online testing for lightning arresters? The purpose of online testing for HV lightning arresters is to evaluate their health and operational condition while they remain energized and connected to the high-voltage system. This non-intrusive testing monitors critical parameters—especially leakage current—to detect early signs of insulation degradation, moisture ingress, or internal damage. By performing these tests without disconnecting the arrester, utilities can ensure continuous protection against transient over voltages, prevent unexpected failures, and schedule maintenance proactively, thereby enhancing system reliability and safety. 02 How does online testing differ from offline testing of lightning arresters? Online testing of lightning arresters is performed while the arrester is energized and connected to the live high-voltage system. It monitors parameters like leakage current and voltage in real time to assess the arrester’s condition without interrupting power supply or removing the arrester from service. Offline testing, on the other hand, requires disconnecting the arrester from the system and applying controlled test voltages or impulses in a laboratory or test environment. This allows detailed diagnostic tests, such as insulation resistance, dielectric withstand, and energy absorption capability, but causes downtime and power disruption. In summary, online testing enables continuous condition monitoring without service interruption, while offline testing offers more comprehensive diagnostics but requires taking the arrester out of operation. 03 What parameters are measured during online testing of lightning arresters? During online testing of lightning arresters, the key parameters measured include: Leakage current: Both resistive and capacitive components are monitored to detect insulation deterioration or moisture ingress. Discharge current: Measures the arrester’s response to transient overvoltages. Voltage across the arrester: To correlate leakage current with operating voltage. Power factor (dissipation factor): Indicates the level of insulation losses and ageing. Harmonic content of leakage current: Helps identify partial discharges or defects. Continuous monitoring of these parameters helps identify early signs of failure and evaluate arrester condition in real time. 04 What types of leakage current patterns indicate a failing arrester? In surge arresters (typically metal oxide varistor or MOV-based), leakage current patterns can offer early warning signs of deterioration or failure. Here are the key types of leakage current patterns that indicate a failing arrester: 1. Increasing Total Leakage Current Over Time What it means: The arrester is gradually losing its insulation resistance. Cause: Ageing of the zinc oxide blocks or moisture ingress. Warning: A consistent upward trend is a red flag — especially under normal system voltage. 2. High Resistive Leakage Current What it means: An increase in resistive (non-linear) current indicates internal degradation. Why it's critical: Unlike capacitive leakage (which is normal), resistive leakage is a sign of arrester deterioration. How it shows up: Measured using third-harmonic analysis or waveform separation techniques. 3. Sudden Jumps or Spikes in Leakage Current What it means: Possible internal flashover, moisture ingress, or external contamination. Typical sign: A sharp increase without a gradual trend. Next step: Immediate inspection or replacement is usually advised. 4. Leakage Current with Strong Daily Variation What it means: Leakage current rises during daytime due to heating and falls at night — abnormal if variation is large. Potential cause: Moisture or contamination interacting with thermal cycles. 5. Phase Shift Changes in Leakage Current What it means: The phase angle between voltage and leakage current shifts — especially the third harmonic. Used in: Online monitoring systems. Why it matters: Indicates the balance between capacitive and resistive components is shifting unfavourably. 6. Leakage Current under Wet Conditions What it means: If leakage current increases dramatically during rain or fog, it may indicate surface tracking or contamination. Action: Cleaning or replacing the arrester may be required. 05 Which standard is most widely accepted worldwide? The IEC 60099-4 standard (from the International Electrotechnical Commission) is the most widely accepted global standard for metal-oxide lightning arresters. It defines performance criteria, testing procedures—including online monitoring methods—and requirements for high-voltage arresters used in power systems. The B2 method for assessing leakage current in metal-oxide surge arresters is detailed in the IEC 60099-4 standard — specifically in IEC 60099-4:2013, titled "Surge arresters — Part 4: Metal-oxide surge arresters without gaps for AC systems — Methods of test". This standard outlines how to measure and analyze leakage current components, including the resistive part used in the B2 method, for condition assessment and online monitoring of high-voltage lightning arresters. 06 Do you know Which parameter are measured in IEC 60099-4 B2 Method ? In the B2 method, leakage current measurement is used to evaluate the condition of a metal-oxide lightning arrester by analyzing its resistive (non-capacitive) leakage current component while the arrester is energized at operating voltage. Here’s how it works: Measurement: The total leakage current flowing through the arrester is measured using sensitive instruments. This current consists of a capacitive component (normal and stable) and a resistive component (indicative of arrester aging or damage). Resistive component isolation: The B2 method focuses on isolating the resistive part of the leakage current, as an increase in resistive current usually signals degradation, moisture ingress, or damage to the arrester’s internal varistors. Analysis: By comparing the measured resistive leakage current to baseline or manufacturer’s reference values, the condition of the arrester can be assessed. A rising resistive leakage current over time indicates deteriorating insulation and the potential for failure. Trend monitoring: Periodic measurements allow trend analysis, helping predict the arrester’s remaining life and plan maintenance before catastrophic failure occurs. This method is widely used because it is sensitive, non-invasive, and can be performed online without disconnecting the arrester. 07 Which compensations are taken care in B2 method typically In the B2 method, leakage current measurement is used to evaluate the condition of a metal-oxide lightning arrester by analyzing its resistive (non-capacitive) leakage current component while the arrester is energized at operating voltage. Here’s how it works: Measurement: The total leakage current flowing through the arrester is measured using sensitive instruments. This current consists of a capacitive component (normal and stable) and a resistive component (indicative of arrester aging or damage).
